Background Patients with type 2 diabetes have an increased risk of developing microvascular and macrovascular complications. In routine diabetes care an adequate reduction of risk factors for these complications is often not achieved.
Objective The aim of the study was to evaluate the effects of structured diabetes care on clinical outcomes of patients with type 2 diabetes in primary care.
Methods We performed a quasi-experimental study on the effects of structured care consisting of organizational and educational components (n = 581) compared with care-as-usual (n = 152). We assessed clinical outcomes of HbA1c, blood pressure, cholesterol, creatinine and body mass index, at baseline and after 1 year. The long-term effects in the structured care group were determined after another 2 years.
Results Structured care led to improvement in HbA1c and long-term improvements in blood pressure and cholesterol compared with care-as-usual. After 1 year, the percentage of patients who did not deteriorate was higher in the structured care group, again for HbA1c, diastolic blood pressure, low-density lipoprotein cholesterol and body mass index.
Conclusions Structured diabetes care consisting of multiple components has a positive effect on clinical outcomes compared with care-as-usual. Our findings support its further implementation in order to reduce complications in type 2 diabetes patients.
